Isograph P 0.35mm
Ref. : 181 035
Production Date : unknown
A not-so-common Isograph. This is a « P » model, which means this pencil was designed for drawing on Polyester uncoated drafting film. It’s the same design as a regular Isograph. Visually the main difference being the medium grey color of the body/cap instead of the usual brown. The tip of the nib is made of stronger metal specially designed for polyester films. It’s the only Isograph of this kind I’ve got, so I don’t know how many nib size were available. I guess the usual range of Iso 3098-128 were produced as the box bears the logo ISO 3098. I need to investigate further, but infos are hard to get about this line of pencils. Please forgive the poor quality of the pictures, my camera is slowly passing away… I need a new one!
